Audi unveils A3 Sportback G-Tron with bi-fuel power, 808-mile range

By this time next year, the Audi A3 Sportback will be offered with a variety fuel-efficient powertrains ranging from diesel to the all-electric E-Tron, but perhaps the most interesting is the all-new G-Tron model, which uses Audi's innovative carbon-natural compressed natural gas called e-gas. Previously called A3 TCNG, we first heard about this technology last year, but now Audi has confirmed that this low-emission, sustainable-fuel will debut by the end of this year on the A3 Sportback G-Tron.
To create this e-gas, a plant in Werlte, Germany uses electricity to split water into hydrogen and oxygen. As hydrogen fuel cell vehicles become more popular, Audi says that this process could also be used to produce hydrogen fuel, but to create CNG, it mixes the hydrogen with carbon dioxide to create "synthetic methane." Since it is identical to the CNG available today, Audi's e-gas can be shipped and stored using the existing CNG infrastructure. Making the whole process even greener, Audi obtains the CO2 for this process from a nearby biogas plant, which would otherwise be released into the atmosphere.
Differentiated from the regular versions of the A3, the G-Tron features a pair of tanks under the rear cargo floor holding 15.43 pounds of CNG, which can power the car for almost 250 miles. What's more, the A3's conventional gasoline tank is still in place, giving the car an addition 560 miles of range. In total, that means the A3 G-Tron has a driving range of more than 800 miles. To run on both CNG and gas, Audi made changes to the car's 1.4-liter four-cylinder engine (including the turbo, cylinder head and fuel injection system) and catalytic converter.

Audi bringing new TT Roadster to Paris

The TT may be first and foremost a coupe, but in presenting the third-generation model, Audi has toyed with all sorts of body-styles. There's been the prototypical coupe, of course, but also shooting brake and crossover concepts. The one thing it hasn't shown us is the convertible model, but that ends today as Audi takes the wraps off the new TT Roadster and TTS Roadster.
Set to be unveiled at the Paris Motor Show next month, the new TT Roadster naturally follows its fixed-roof counterpart's lead closely, but with the addition of a folding fabric roof mechanism. Made of magnesium, aluminum, steel and plastic, the mechanism weighs 6.6 pounds less than its predecessor's, helping keep the center of gravity lower. It also folds flatter to allow for more luggage space, and can deploy or retract in ten seconds at speeds up to 31 miles per hour. With the roof up it's also quieter, and with a drag coefficient of 0.30, Audi claims it's the slipperiest in the segment.
Of course, Audi's also worked to keep the weight down and rigidity up. As a result, the 0-62 sprint only takes an extra 0.2 seconds, quoted in the TTS Roadster at 4.9 seconds instead of 4.7 in the TTS coupe. Top speed remains pegged at 155 miles per hour. That, of course, is with the top-spec, 310-horsepower 2.0-liter turbo four, but Audi will also offer the less potent 184-hp version as well as a 2.0-liter TDI, mated to either a six-speed manual or six-speed DCT, though specific performance figures for each version were not disclosed in the press release below.

2015 Audi Q3 is ready to woo America's young and upwardly mobile

You can hardly blame Audi for its decision to finally bring its Q3 compact crossover to America, even though it's been on sale in other global markets since 2012. CUVs of all stripes are red hot, and the number of players in the US entry-level premium segment is mushrooming. Rapidly growing Audi simply can't afford to be left out of the discussion in favor of vehicles like the BMW X1, Land Rover Range Rover Evoque, and even small near-luxury entries like the Buick Encore, if only because capturing these customers could result in subsequent sales of more profitable models down the road.
Audi evidently intends to attract these new, younger customers by spoiling them in decidedly unGermanic fashion: by offering lots of standard equipment. Peruse the spec sheet on base models from rivals and you'll see things like manually adjusted faux leather seats, conventional projector headlamps, and little in the way of frills. By comparison, the 2015 Q3 comes with an embarrassment of standard features, including heated and power-articulated leather seats, panoramic moonroof, Xenon headlamps with LED accents and keyless start.
First impressions of the four-cylinder, 200-horsepower Q3 revealed here at the Detroit Auto Show are very positive, with a rakish (if overly familiar) shape and a fair amount of utility with up to 48.2 cubic feet of storage with the rear seats folded. If Audi can price the Q3 similarly to the entry-level BMW X1 sDrive28i ($31,825 delivered) when it arrives this fall, we think it'll sell like hotcakes - just like its Q5 big brother.
